We haven't had any imaging done since she was born but at the time they were just ruling out spina bifida. There are several outward signs that could include a dimple. The other thing I found in some of the reading is that a birthmark puts you at a higher risk and it is congenital which wouldn't surprise me with the other issues she has had. Also a low muscle tone but that is hard to know if it is related to CMTC. The image usually done is an MRI. I am going to get through my physical therapy and my appointment with the doctor that did my brain surgery this week and I will schedule an appointment with our family doctor next week. Then we can discuss who to see and if we need to look furhter. She really needs another thyroid test anyway so I can get that done at the same time.
